JPS6144022A - Automatic opening device for car window - Google Patents

Abstract

PURPOSE:To enable a car window to be slightly opened with a one-touch operation by constructing the captioned device in such way that a window opening- closing driving mechanism can be driven in the window opening direction for a defined time by switching a car window opening-closing means to a specified position. CONSTITUTION:When a switch 1 is thrown into a contact 1a (or 1b), a relay 3 (or 2) is energized while the switch is being thrown in, causing a motor 4 to be driven to the car window closing (or opening) side. On the other hand, when the switch 1 is thrown into a contact 1c, a transistor Tr6 is turned on, causing a capacitor C7 to be charged via a resistor 8. Thereupon, since the inverted input terminal voltage of a comparator 5 becomes lower than a non-inverted input voltage, an output terminal (a) becomes an H level, transistors Tr9, Tr10 are turned on in order energizing the relay 2, and the motor 4 is rotated to the lowering side. And, when the charged voltage of the capacitor C7 becomes above the voltage of the non-inverted input terminal after a defined time, the output terminal (a) becomes an L level, and the relay 2 is deenergized causing the motor 4 to stop.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an automatic vehicle window opening/closing device.

[Prior art]

Conventional devices are configured to open or close a vehicle window in response to a switch operation, and more improved devices are configured to maintain open or closed operation until the vehicle window is fully opened or closed. .

[Problem that the invention seeks to solve]

Therefore, in order to perform a slight opening operation to let in a small amount of outside air or to expel cigarette smoke, it was necessary to continue operating the switch for a necessary period of time. The aim is to eliminate the hassle of operation.

[Means for solving problems]

For this reason, the device of the present invention includes a drive mechanism that is directly connected to a window of a vehicle to open the window in a first operating state and closes the window in a second operating state, and a drive mechanism that is operated when opening the window to open the window in a first operating state and close the window in a second operating state.・1
an operating means that generates an operating signal, is operated to generate a second operating signal when the window is closed, and is operated to generate a third operating signal when the window is slightly opened; and the third operating signal and a drive means for generating and applying to the drive mechanism a drive signal necessary to place the drive mechanism in the first operating state for a predetermined period of time in response to the drive mechanism.

[Effect]

Thus, when it is desired to open the vehicle window slightly, the operating means is operated to generate the third operating signal, and the driving means causes the drive mechanism to be in the first operating state for a predetermined period of time. As a result, the vehicle window is opened by the opening degree corresponding to this time length, and is stopped in the open state.

〔Effect of the invention〕

Therefore, according to the present invention, it is possible to open and close the vehicle window in the same manner as before, and it is also possible to slightly open the vehicle window by a single operation.

〔Example〕

In FIG. 1 showing the first embodiment, 1 is a window switch which is normally placed in a neutral state. 2.3 is a motor drive relay, 4 is a window motor directly connected to the window, 5 is a comparator, a is a positive output terminal, and b is an inverted output terminal. 6 is a transistor that operates in conjunction with switch 1, 7 is a capacitor, and 8 is a resistor, and together they define the one-shot time. 9.10 is a relay driving transistor. Reference numeral 11 represents a resistor that is involved when the capacitor 7 is discharged. 60 is a drive circuit that generates a drive signal for driving the relay 2 in response to the operation signal of the switch 1.

In the above configuration, when the switch 1 is connected to the first contact 1a, the relay 3 is energized while the switch 1 is in contact with the first contact 1a, and the motor 4 is
is rotationally driven in the upward direction (the direction in which the vehicle window is closed). Further, when the second contact 1b is contacted, the relay 2 is energized and the motor 4 is driven downward (-1 (opening direction)) in the reverse direction.

By the way, when the switch 1 enters the third contact 1c, the transistor 6 is turned on, and the capacitor 7 is charged through the resistor 8. At this time, the inverting input terminal voltage of comparator 5 is
Since it is lower than the non-inverting input, the output terminal a becomes Hi level, transistor 9 is turned on, and transistor lO is turned on.
is turned on, so relay 2 is energized. Therefore, the motor 4 rotates in the downward direction.

Next, when the charging voltage of the capacitor 7 exceeds the voltage of the non-inverting input terminal after a predetermined period of time, the output terminal a of the comparator becomes a Lo level and the output terminal b becomes a Hi level, the relay 2 is deenergized and the motor is stopped. At this time, if the value of the resistor 11 is small, the capacitor 7 is discharged quickly, so that this motor driving operation can be repeated continuously. Note that by adjusting the time constants of the resistor 8 and the capacitor 7, the stop position (or stop interval) of the window can be set.

A second embodiment is shown in FIG. Reference numeral 70 denotes a position detection switch, which is turned on when the window is 10 cm from the top, and turned off at other positions. 60 is a one-shot multi-by-break similar to that in FIG.

When the switch 1 enters the third contact, the one-shot multi-bye break 60 is triggered. At this time switch 7
If 0 is closed, the output of the AND gate 71 becomes Hi level, the relay 2 is energized, and the motor moves in the downward direction.

Next, the output of one shot multi-by break 60 is LO
When the level is reached or the switch 70 is opened, the gate 7
The output of motor 1 becomes Lo level, and motor 4 stops. In this example, the opening position can be changed depending on the position of the switch 70.

A third embodiment is shown in FIG. 81 is a Seso i restoration R3-flip-flop, 90 is a cent input terminal, 9
1 is a recent input terminal, and 92 is an output terminal. 80 is an inverter. When switch 1 enters the third contact,
When the position detection switch and chia 0 are closed, flip-flop 8
The input 90 of 1 becomes Hi level, and the output 92 becomes H level.

Furthermore, since the relay 2 is energized, the motor 4 rotates in the downward direction. Next, when the switch 70 is opened, the input terminal 91 of the flip-flop 92 becomes the H level, so the output 92 becomes the Lo level, the relay 2 is deenergized, and the motor 4 is also stopped.
